Non-native tree in arboretum

 

Comment:

Several different Eucalyptus trees, non-native to the US, were planted in the very diverse Boyce Thompson Arboretum to form a small grove. I could not find a name marker for this one. Its partly-deciduous bark makes for a very interesting light/dark pattern in both UV and visible light.

Hello Andrea,

 

You probably know what I'm going to say. Eucalypts are difficult to ID from the bark, a guess would be E. camaldulensis River Red Gum, but the definitive way is to see the leaves, buds, flowers and fruit.
